有机可逆热致变色材料的变色机理及应用进展

Color-changing Mechanism and Application Development of Organic Reversible Thermochromic Materials

有机可逆热致变色材料低温变色性能优于传统的无机可逆变色材料,已受到广泛的关注。目前,研究与开发的有机可逆热致变色材料已不少,其变色机理不尽相同。重点介绍了分子结构的变化对有机可逆热致变色材料变色机理的影响,并概述了有机可逆热致变色材料的应用。

The low temperature color-changing properties of organic reversible thermochromic materials are su perior to traditional inorganic materials and have aroused wide concern. Recently, so many thermochromic materials have been developed, but they have different color-changing mechanism. The effects of molecular structural changes on color-changing mechanism of organic reversible thermochromic materials are introduced. Applications of organic reversible thermochromic materials are reviewed.
